Larkspur Nielsen is determined to keep her family homestead running and to fulfill their dream of starting a seed catalog, with or without her siblings' help. With Isaac McTavish back in town, Lark finds herself at odds with her own heart and her determination to shoulder the burden of carrying her responsibilities alone. But Isaac is set on convincing her that he's here to stay and she doesn't have to carry everything by herself.

As a new romance blossoms between Lilac and an old schoolmate and the other Nielsen sisters are busy caring for their families, Lark bears more and more responsibility on the farm. When a long-feared threat returns and Lark approaches the breaking point, the life she has always dreamed of is in danger of disappearing forever.
